Hillary and her crew are grasping at straws. As her campaign is falling apart, they have nothing to accuse Trump of anymore. They’ve released all they had and people have abandoned that information for the sh*t show that is Hillary’s campaign.

For much of the summer, the F.B.I. pursued a widening investigation into a Russian role in the American presidential campaign. Agents scrutinized advisers close to Donald J. Trump, looked for financial connections with Russian financial figures, searched for those involved in hacking the computers of Democrats, and even chased a lead — which they ultimately came to doubt — about a possible secret channel of email communication from the Trump Organization to a Russian bank.

Law enforcement officials say that none of the investigations so far have found any conclusive or direct link between Mr. Trump and the Russian government. And even the hacking into Democratic emails, F.B.I. and intelligence officials now believe, was aimed at disrupting the presidential election rather than electing Mr. Trump.

Hillary Clinton’s supporters, angry over what they regard as a lack of scrutiny of Mr. Trump by law enforcement officials, pushed for these investigations. In recent days they have also demanded that James B. Comey, the director of the F.B.I., discuss them publicly, as he did last week when he announced that a new batch of emails possibly connected to Mrs. Clinton had been discovered.

Supporters of Mrs. Clinton have argued that Mr. Trump’s evident affinity for Russia’s president, Vladimir V. Putin — Mr. Trump has called him a great leader and echoed his policies toward NATO, Ukraine and the war in Syria — and the hacks of leading Democrats like John D. Podesta, the chairman of the Clinton campaign, are clear indications that Russia has taken sides in the presidential race and that voters should know what the F.B.I. has found.

The F.B.I.’s inquiries into Russia’s possible role continue, as does the investigation into the emails involving Mrs. Clinton’s top aide, Huma Abedin, on a computer she shared with her estranged husband, Anthony D. Weiner. Mrs. Clinton’s supporters argue that voters have as much right to know what the F.B.I. has found in Mr. Trump’s case, even if the findings are not yet conclusive.

“You do not hear the director talking about any other investigation he is involved in,” Representative Gregory W. Meeks, Democrat of New York, said after Mr. Comey’s letter to Congress was made public. “Is he investigating the Trump Foundation? Is he looking into the Russians hacking into all of our emails? Is he looking into and deciding what is going on with regards to other allegations of the Trump Organization?”

Mr. Comey would not even confirm the existence of any investigation of Mr. Trump’s aides when asked during an appearance in September before Congress. In the Obama administration’s internal deliberations over identifying the Russians as the source of the hacks, Mr. Comey also argued against doing so and succeeded in keeping the F.B.I.’s imprimatur off the formal findings, a law enforcement official said. His stance was first reported by CNBC.

Senator Harry Reid of Nevada, the minority leader, responded angrily on Sunday with a letter accusing the F.B.I. of not being forthcoming about Mr. Trump’s alleged ties with Moscow.

“It has become clear that you possess explosive information about close ties and coordination between Donald Trump, his top advisers, and the Russian government — a foreign interest openly hostile to the United States, which Trump praises at every opportunity,” Mr. Reid wrote. “The public has a right to know this information.”

F.B.I. officials declined to comment on Monday. Intelligence officials have said in interviews over the last six weeks that apparent connections between some of Mr. Trump’s aides and Moscow originally compelled them to open a broad investigation into possible links between the Russian government and the Republican presidential candidate. Still, they have said that Mr. Trump himself has not become a target. And no evidence has emerged that would link him or anyone else in his business or political circle directly to Russia’s election operations.

At least one part of the investigation has involved Paul Manafort, Mr. Trump’s campaign chairman for much of the year. Mr. Manafort, a veteran Republican political strategist, has had extensive business ties in Russia and other former Soviet states, especially Ukraine, where he served as an adviser to that country’s ousted president, Viktor F. Yanukovych.
